Description

Technical Field

[0001] The invention relates to a bead foaming post-processing device and a use method thereof. Background Art

[0002] Expanded Polystyrene (EPS) is a lightweight polymer. It is the abbreviation of a new type of foam plastic. It is made by adding a foaming agent to polystyrene resin, heating it to soften it, and generating gas to form a rigid closed-cell foam plastic. EPS has a light specific gravity, good elasticity, shock and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance (-40 to 130°C), non-toxic and tasteless. It is a foam plastic with excellent functions. The EPS molding process includes pre-foaming, molding and drying. Pre-foaming is to heat the beads in a pre-foaming machine. After the beads are heated and softened, the volume expands and reaches the required foaming ratio. The foamed EPS beads are molded into EPS products of various shapes in the molding machine.

[0003] At present, in the prior art, the pre-foamed EPS beads are placed in a silo for a certain period of time to balance the external pressure inside the bead pores, make the beads elastic and have re-expansion ability, and remove moisture from the surface of the beads. The aging time is 8 to 48 hours, and the waiting time is relatively long. How to overcome the above-mentioned defects has become an important issue that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0007] In the bead foaming post-processing device as described above, the exhaust mechanism 23 is arranged on the top of the processing chamber 2.

[0008] In the bead foaming post-processing device as described above, the wall of the processing chamber 2 is made of a heat-insulating material or a heat-insulating material layer is provided on the wall of the processing chamber 2 .

[0009] In the bead foaming post-processing device as described above, the processing chamber 2 extends laterally, and a support net 26 for supporting foamed beads is provided in the processing chamber 2. The stirring mechanism 24 is located above the support net 26, and the discharge drive mechanism 25 includes a blower 251 for blowing air from the lower end of the support net 26 to drive the foamed beads at the upper end of the support net 26 to be output.

[0010] In the bead foaming post-processing device as described above, the stirring mechanism 24 includes a stirring motor 241, a horizontal rotating shaft 242 driven to rotate by the stirring motor 241, a plurality of connecting rods 243 vertically connected to the horizontal rotating shaft 242, and a plurality of rubber plates 244 installed on the connecting rods 243 for carrying foamed beads, and the horizontal rotating shaft 242 is extended forward and backward.

[0011] In the bead foaming post-processing device as described above, a radiator 252 for heating wind is provided on the blower 251 , and the radiator 252 is connected to the high-temperature exhaust port of the foaming barrel 1 through a pipeline.

[0012] In the bead foaming post-processing device as described above, the discharging drive mechanism 25 further includes an inclined upward air guide plate 253 disposed at the lower end of the support net 26 for guiding the air of the blower 251 obliquely upward.

[0013] In the bead foaming post-processing device as described above, the support net 26 extends to behind the discharge valve 22 , and the upward inclined air guide plate 253 is arranged below the section of the support net 26 behind the discharge valve 22 .

[0014] As mentioned above, this case also protects a method for using a bead foaming post-processing device, comprising the following steps:

[0015] The feeding step includes closing the discharge valve 22 of the processing chamber 2, opening the feed valve 21, operating the exhaust mechanism 23, and closing the feed valve 21 after the feeding is completed;

[0016] The step of stirring the materials is to operate the stirring mechanism 24 to stir the materials;

[0017] In the step of discharging, the discharging valve 22 is opened, and the discharging driving mechanism 25 is operated to drive the foamed beads in the processing chamber 2 to be discharged.

[0018] In the method for using the bead foaming post-processing device as described above, in the discharging step, the discharging driving mechanism 25 drives the foamed beads in the processing chamber 2 to be discharged by blowing air.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The structure of the post-processing device for foaming beads in this case is simple and easy to implement. The processing chamber is connected to the outside of the foaming barrel and is provided with a feed valve. In this way, after closing the feed valve, the processing chamber and the foaming barrel do not affect each other, which is beneficial to improving the foaming utilization rate of the foaming barrel. The post-processing of beads after foaming by this device is beneficial to avoid the defect that the beads need to wait for a long maturation time in the foaming barrel after foaming, and it is practical. Since the processing chamber is provided with an exhaust mechanism, on the one hand, it is convenient to form a negative pressure for convenient feeding, and on the other hand, it is convenient to extract the moist air coming in from the foaming barrel together with the foaming beads, which plays a role in drying the foaming beads and is beneficial to shortening the maturation time. The setting of the stirring mechanism is convenient for stirring so that the foaming beads do not stick together, which is practical.

[0021] 2. The exhaust mechanism is arranged on the top of the processing chamber, so that it is not easy to be blocked by the foam beads in the processing chamber and the foam beads are not easy to be extracted when exhausting, which has good practicality.

[0022] 3. The horizontal rotating shaft of the stirring mechanism in this case is extended forward and backward, which is convenient for installation on the front wall or the rear wall or between the front and rear walls of the processing bin. The setting of the rubber plate on the connecting rod facilitates soft contact with the foaming beads.

[0023] 4. The horizontally extended setting of the processing chamber described in this case facilitates the lateral dispersion and reduces the stacking height of the foamed beads, which is beneficial to the flow of air on the surface of the foamed beads; the setting of the support net in the processing chamber, on the one hand, facilitates the moisture in the foamed beads thereon to fall to the bottom of the support net under the action of gravity, and on the other hand, facilitates the blowing of the foamed beads. Its layout is good and practical.

[0024] 5. The setting of the radiator described in this case, on the one hand, is conducive to increasing the temperature of the air blown into the processing chamber by the blower so as to reduce the impact on the foaming beads, and on the other hand, is conducive to the reuse of the waste heat of the high-temperature gas in the foaming barrel, and has good practicality.

[0025] 6. The support net extends to behind the discharge valve, and the upward inclined air guide plate is arranged below the support net section behind the discharge valve. In this way, even if the discharge valve is closed, it will not affect the output of the foamed beads remaining after the blower drives the discharge valve.

[0026] 7. The method of using the bead foaming post-processing device in this case is simple and practical. When the exhaust mechanism is operated during feeding, on the one hand, it is convenient to form a negative pressure to facilitate feeding, and on the other hand, it is convenient to extract the moist air coming in from the foaming barrel together with the foaming beads, which plays a role in drying the foaming beads and is beneficial to shortening the aging time; after the feeding is completed, the feeding valve is closed to prevent the processing chamber from communicating with the foaming barrel, so that the foaming barrel can carry out another foaming work, which is beneficial to improve the use efficiency of the foaming barrel; then the stirring mechanism is used to stir the material, so that the foaming beads do not stick together, which is practical.

[0027] 8. The discharging drive mechanism drives the foam beads in the processing chamber to be discharged by blowing air, so that the foam beads are not easily deformed due to pressure. BRIEF DESCRIPTION OF THE DRAWINGS
